I've never had a page appear/popup in the manner you describe and heck my popupblocker is off at present (has been for ages and Ive just not turned it back on). I have had it were a bar ad will sneak down the page in a ghost form - that is clicking activates the ad, but the image of the ad itself does not appear. However scrolling the window up to show the ad reverts the ghosting effect. I've not really noticed that its a TPF thing above any other site with an adbar and just assumed it was some quirk occuring.

What happens to me is, I go to Active Topics, it loads up and when I go to click on a thread, it jumps like something just loaded and caused the page to move to accommodate the space taken up by whatever loaded (a photo for example). When it jumps, you end up clicking something you didn't intend on clicking.

Most of the time it takes me to peoples profile pages. The work around it is waiting longer after a page loads.

Odd I don't get that occuring at all - the closest I get is opera reising the tab size when it fully loads a page if it happens to have a short title but the page itself remains unchanged (its only a pain when opening and closing tabs in quick sucession).

But the page moving around I've not come across - though I tend to surf newposts as opposed to active topics.
